Comparison of zooplankton vertical migration in an ice‐free and a seasonally ice‐covered Arctic fjord: An insight into the influence of sea ice cover on zooplankton behavior

We present observations of zooplankton diel vertical migration (DVM) over a period of 2 yr in an ice‐free and a seasonally ice‐covered Arctic fjord. The contrasting environments permitted assessment of the influences of physical and biological factors on temporal variability in DVM patterns and a test of the hypothesis that a reduction in summer sea ice extent and thickness following climatic warming will lead to changes in DVM via the loss of a...
